1. Oral Use of Phenytoin to Reduce Calcification in Bovine Pericardium and Porcine Aortic Leaflets Implants in Rats
Abstract Introduction: This study aims to test the effect of phenytoin as an inhibitor of the process of dystrophic calcification in bovine pericardium and porcine leaflets implanted in the subcutaneous tissue of rats. Methods: Isolated segments of biomaterials were implanted subcutaneously in young rats. The study groups received 500 mg phenytoin per kilo

2. Desenvolvimento de membranas acelulares de colágeno derivadas de pericárdio porcino para uso em engenharia de tecido / Development of acellular collagen membranes derived from porcine pericardium with potential application in tissue engineering
A utilização e o desenvolvimento de biomateriais para a regeneração tecidual são de grande importância, principalmente para a área médica e odontológica. Matrizes de colágeno derivadas de tecidos de origem animal são utilizadas devido o colágeno apresentar características como biodegradabilidade e biocompatibilidade. Essas matrizes podem ser obt

3. Estudo comparativo da biocompatibilidade in vivo de matrizes acelulares de pericárdio bovino e porcino / In vivo biocompatibility study of acellular bovine and porcine pericardium matrices
Acellular matrices are used in tissue engineering for reconstruction or replacement of damaged tissues .In this study acellular matrices were developed using porcine pericardium and bovine pericardium, which contain a large quantity of type I collagen, using an alkaline hydrolysis treatment at the times of 12 hours and 24 hours. The matrices were developed t

4. Laser de baixa intensidade no tratamento de úlceras cutâneas aplicando curativos de pericárdio porcino revestido com quitosana / Low level laser therapy for treatment of skin ulcers by applying dressings porcine pericardium coated with chitosan
As lesões na pele, quando extensas, representam um grande problema de saúde pública e elevados custos associados aos tratamentos. A laserterapia tem sido aplicada por décadas a fim de acelerar o processo de cicatrização cutânea. Já a matriz de pericárdio porcino apresenta potencial para ser utilizado como curativo biológico, porém o patch tem ráp

5. Mineralização in vitro de matrizes de colágeno aniônico derivadas de tecidos biológicos / In vitro mineralization of anionic collagen matrices
The reconstruction of osseous defects is still a problem that affects millions of people and medicine tries to solve it. One alternative to solve these problems has been the development of biomaterials that can be used as inductors in the osseous repair process. Collagen is a natural polymer able to promote healing and bone regeneration, and among hydroxyapa

6. Matriz extracelular de pericardio fibroso porcino : estudo morfologico e bioquimico / Extracellular matrix of porcine fibrous pericardium: morphological and biochemical study
Pericardial tissue has been used to construct bioprostheses employed in the repair different kinds of injuries. However, calcification and mechanical failure have been the main causes of limited durability of cardiac bioprostheses constructed with bovine pericardium. In the course of this work a study has been conducted on the porcine fibrous pericardium and

7. Bicuspid mitral bioprosthesis.
A bicuspid mitral bioprosthesis was prepared by mounting glutaraldehyde-processed porcine pericardium onto commercially available Brownlee-Yates stents. The bioprostheses were inserted into 17 dogs. Haemodynamic performance and long-term function of the valve was assessed. Of the 11 animals in the survival group, eight died within the 24-72 hour postoperativ

8. Rastelli procedure for transposition of the great arteries, ventricular septal defect, and left ventricular outflow tract obstruction. Early and late results in 41 patients (1971 to 1978).
Forty-one children with transposition of the great arteries, ventricular septal defect, and left ventricular outflow tract obstruction underwent a Rastelli operation between 1971 and 1978. A homograft valve preserved in an antibiotic solution and extended with A dacron tube was the conduit of choice. Alternatively, conduits with porcine heterografts or valve
